The General (Server) tab appears in the right configuration panel when Settings is selected for a Server. The following shows the configuration fields:
You may limit the upload network bandwidth that Serv-U will use by specifying maximum value here (in Kbytes-per-second). If left blank, the maximum available bandwidth will be used.
This value limits the download network bandwidth that Serv-U will use by specifying maximum value here (in Kbytes-per-second). If left blank, the maximum available bandwidth will be used.
Sets maximum number of simultaneous users. A setting of 0 will allow no users, leaving this option blank will set no limit on the number of users.
'Netiquette' prescribes that users logging into an FTP server under the 'Anonymous' user name should use their E-mail address as their password. When this option is checked, Serv-U will check the passwords that anonymous users enter to log into the server. (These basic checks make sure the password resembles an e-mail address. No verification of valid e-mail addresses is done). If left unchecked the server will accept anything for the anonymous user's password.
If checked, partially uploaded files that did not complete successfully are automatically deleted. By default, this is unchecked, so partial transfers can be resumed where they left off.
For some operating systems it is easier to have to deal with only lower-case, in particular if the OS is case sensitive. Enabling this option will produce directory listings with only lower case for file and directory names and uploaded files with be stored using lower case.
Many FTP client programs have an automatic mechanism that prevents users from being logged out after a certain inactivity time. When checked, Serv-U will count how long a user has been idle in a way that prevents client programs that periodically send automatic commands to the server from keeping idle connections open.
When checked, the server will only allow file transfers between the FTP client and server, and block any direct server-to-server transfers (FXP). This prevents a type of malicious attack known as 'FTP_bounce attacks' (see CERT advisory CA-97.27).
Use this option to protect your FTP server from 'hammer attacks'. When enabled, users are blocked from connecting to your server in rapid succession. If they make more than XX connections within YY seconds their subsequent connections will be terminated immediately upon connection and they will be blocked for the next ZZ minutes. No message is sent to the user when he is blocked, which makes using this option very low overhead for the server. You can view blocked IPs and make changes to them in the Blocked IPs tab of the Activity panel.
